The present disclosure relates to a training aid attachment for bicycles. More particularly, the present disclosure relates to a support wheel adjustment mechanism for a bicycle that easily adjusts support wheels at variable elevations from ground conditions for enabling children to learn to ride bicycle.
When a child (or user) starts to ride a bicycle, child/user may not have the skill to balance bicycle because of dynamic lateral instability of bicycles. While learning to ride a bicycle, a child/user may fall a number of times because of incapability to balance and at some occasions can be badly injured. To avoid such fall and injury, support wheels are attached that touches the ground and provides stability to child/user, however, child/user may not experience the feel of balancing their own body weight on two wheels of bicycle. Over a period of practice, support wheels are removed and a parent or a guardian assist child to keep a balance by holding bicycle. However, even parent or guardian eventually requires letting go the child and learn balancing. At such situations also, the child may fall and get badly injured.
Several designs of various support/auxiliary wheels for bicycles have been designed in the past. None of them, however, include a support wheel mechanism for a bicycle that facilitates easy manipulation/adjustment of support wheels at variable elevations from ground conditions and hence provide experience of self-balancing without fear and enabling children to learn to ride bicycle.
Applicant believes that a related reference corresponds to U.S. Pat. No. 7,556,277 filed by Lytle Kimberly M titled ‘Bicycle training aid with dynamically deployable balancing features’ discloses a mechanism for deploying the balancing mechanisms which is remotely controlled by adult supervisor. However, the mechanism is moreover operable by parent and because of parental control, child may not be able to gain riding confidence as child may not be able to identify and correct upon his/her mistake.
Another U.S. Pat. No. 5,707,069 filed by Brevets Futek M S M Ltee titled ‘Stabilizer training wheel for bicycle’ discloses a side wheel attachment for removably attaching an auxiliary side wheel to a bicycle. However, the disclosure does not explicitly mention on adjusting height of stabilizer training wheel.
Other documents describing the closest subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of these patents suggest the novel features of the present invention.
In view of the above, it is an objective of the present invention to solve or at least reduce the problems discussed above. The present invention is a support wheel adjustment mechanism for a bicycle provided on either side of bicycle. Each support wheel mechanism includes a first element, a second element, a swivel hinge connection, an adjustable element and a fixing element. First element and second element are connected with each other by swivel hinge connection. Adjustable element has one end portion connected with hinge connection with first element and another end portion is selectively connected to any of adjustment openings such that support wheels achieves desired elevation from ground. Adjustable element is secured in adjustment openings by use of fixing element.
It is one of the main objects of the present invention is to provide a support wheel adjustment mechanism for a bicycle that facilitates easy adjustment of support wheel at different elevations from ground and thereby facilitate learning riders to gain gradual balancing and thereby independently gain riding confidence without fear.
It is another object of this invention is to provide a support wheel adjustment mechanism for a bicycle that easily and quickly adjust support wheels at various elevations from ground and hence makes easier for a child to learn to ride a bicycle.
It is another object of this invention is to provide a support wheel adjustment mechanism for a bicycle that has fewer and structurally less complex elements and hence are easy to manufacture and assemble and hence is cost effective.
It is another object of this invention is to provide a support wheel adjustment mechanism for a bicycle that has easy to operate mechanism for adjusting support wheels at desired elevation in less time and efforts.
Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.
With the above and other related objects in view, the invention consists in the details of construction and combination of parts as will be more fully understood from the following description, when read in conjunction with the accompanying drawings in which:
Referring now to the drawings (
First element 30 is an elongated element that is capable to be fixed with frame 20a of bicycle 20. First element 30 is connected to frame 20a by using one or more fastener(s). Typically, fastener(s) is arrangement of bolt and nut. Fasteners can be fixedly inserted in at least one hole 30a provided on first element 30. Fastener(s) enable easy dismantling of first element 30 from frame 20a when desired. Alternatively, the first element 30 can be connected to frame 20a by use of weld joint or can be positioned on a shaft 30b through a bearing. Size of first element 30 can be varied depending on size and different types of bicycles. Material for first element 30 is preferred to be metallic for longer durability, however, polymeric or any other type of material or combination of materials is within the scope of the present disclosure.
Second element 40 is also an elongated element which has one end portion connected to first element 30 by using swivel hinge connection 50. Connection of second element 40 and first element 30 by using swivel hinge connection 50 provides desired relative motion therebetween. Though, the present disclosure is described by using swivel hinge connection 50 for connecting second element 40 and first element 30, however, the present invention is not limited to use of swivel hinge connection 50 and other types of connection/joints that can provide relative movement of second element 40 and first element 30 are within the scope of the present disclosure. Another end portion of second element 40 is configured to receive a support wheel 80.
Second element 40 is positioned substantially transverse to first element 30 basically forming an L-shaped structure. Second element 40 has a plurality of adjustment openings 40a. In a depicted embodiment, there are four adjustment openings 40ai, 40aii, 40aiii, 40aiv provided, however, less or more number of adjustment openings 40a is within the scope of the present disclosure. Size of second element 40 can be varied depending on requirement of number of adjustment openings 40a. Material for second element 40 is preferred to be metallic for longer durability, however, polymeric or any other type of material or combination of materials is within the scope of the present disclosure.
Adjustable element 60 has a first end portion 60a and a second end portion 60b. First end portion 60a is pivotally connected to first element 30. Second end portion 60b is removable connected with desired adjustment opening 40a by using fixing element 70. Moreover, as illustrated, there are four adjustment openings 40ai, 40aii, 40aiii, 40aiv and second end portion 60b, in one instance, can be connected to any one of four adjustment openings 40ai, 40aii, 40aiii, 40aiv. As shown in
In one embodiment, the width of adjustable element 60 is less than the width of first element 30 and second element 40 and the width of second element 40 is less than the width of first element 30. Such change in width provides easy fitment over each other. However, the width of at least two of first element 30, second element 40 and adjustable element 60 can be equal in size.
Fixing element 70 is manipulated by child/user to fix another end portion of second end portion 60b with any one of adjustment openings 40ai, 40aii, 40aiii, 40aiv. In an exemplary embodiment, fixing element 70 is a removable pin. Alternatively, fixing element 70 can be any other fasteners that can easily create connection and disconnection between second end portion 60b and any of adjustment openings 40. Fixing element 70 can be an independent element or can be configurable to be an integrated part of second end portion 60b and adjustment openings 40, for instance, push and lock mechanism in which when second end portion 40b is pushed in adjustment openings 40ai, second end portion 40b gets locked in any adjustment openings 40 and when pulled second end portion 40b gets un-locked in any adjustment openings 40. Fixing element 70 is connected manually or can be connected automatically by used of actuating mechanism (not illustrated in Figures).
As support wheel adjustment mechanisms 10 provided on either side of bicycle 20 provides gradual learning of balancing of bicycle 20 and hence removes fear from child/user mind and also helps them to independently learn balancing without any support from parent or guardian. Further, adjustment of elevation of support wheel 80 is easy task with less efforts and requirement of any external tool. Support wheel adjustment mechanism 10 for a bicycle that has fewer and structurally less complex elements and hence are easy to manufacture and assemble and hence is cost effective.
